Create below build. I have also specified the JDK version I will be using for our application. File download example using Spring REST Controller does not many dependencies and you need to add only spring boot started web for downloading a file. I am creating below application. I do not need to create any datasource explicitly as I am using the standard naming conventions for database configurations and Spring Boot will automatically create one for us. Create below entity class that maps to database table.
Our entity class has only three fields employee id, employee first name and employee last name. I am creating entity class because I want to create a file from our database record and finally download the file using Spring REST service.
You can build any type of file, such as excel file, csv file etc. So create below Spring Data JPA Repository which provides most of our built-in methods to query database for fetching data.
I fetch all employees from the database using the below service layer code. I annotate the service layer class using Service.
I create service layer class to process our business logic to avoid any tight coupling between the layers. I use the data type as array of byte stream in the response to download the file.

Adding a trigger to an asset that already has one will update the trigger with the latest specified values. Note: An asset can have one trigger and one DQW applied to it at the same time. Use one of the following values:. Optional Status of the trigger. Values can be " true " or " false ". If set to " true ", either the extract data source is monitored for refresh failures or the flow is monitored for flow run failures. If a failure occurs, an alert is applied or replaces an existing one to either the extract data source or flow.
The alert remains there until the next successful refresh or flow run. If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to add quality warning triggers:.
If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to add table asset permissions:. If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to add tags:.
If the data source is already tagged with a tag that's included in the request body, those tags are ignored and the data source retains them. Tableau Server users who are not server administrators or site administrators can call this method only if they have Read permissions for the data source either explicitly or implicitly.
Version 1. If the view is already tagged with a tag that's included in the request body, those tags are ignored and the view retains them. Tableau Server users who are not server administrators or site administrators can call this method only if they have Read permissions for the view either explicitly or implicitly.
If the workbook is already tagged with a tag that's included in the request body, those tags are ignored and the workbook retains them. Tableau Server users who are not server administrators or site administrators can call this method only if they have Read permissions for the workbook either explicitly or implicitly.
This method can only be called by server administrators and site administrators, and by users who are owners of the specified alert. Note : After you create a resource, the server updates its search index. If you make a query immediately to see a new resource, the query results might not be up to date. This method can only be called by server administrators and site administrators.
If Tableau Server is configured to use local authentication, the information you specify is used to create a new user in Tableau Server. Note : After creating the user, you must set a full name, password, and email address for the user with the call to Update User. Even if it is not used by SAML, the user information must be present. If Tableau Server is configured to use Active Directory for authentication, the user you specify is imported from Active Directory into Tableau Server.
When you add user to Tableau Online, the name of the user must be the email address that is used to sign in to Tableau Online.
After you add a user, Tableau Online sends the user an email invitation. The user can click the link in the invitation to sign in and update their full name and password. If you try to add a user using a specific site role but you have already reached the limit on the number of licenses for your users, the user is added as an unlicensed user.
In that case, the response code is which indicates success , but the siteRole value in the response body is set to Unlicensed. If the server uses local authentication, this can be any name. If you are using Active Directory authentication, or if you are using Tableau Online, there are specific requirements for the name.
For most Active Directory users, these attributes are the same. By default, if you are adding a user from Active Directory, the name that you provide in the user-name is matched against the Active Directory sAMAccountName attribute, which becomes the name that the user signs in to Tableau Server with.
Two exceptions are when the name that you provide: is longer than 20 characters; and includes an character. For Tableau Online: The user-name is the email address that the user will use to sign in to Tableau Online. When you add a user to the site, Tableau Online sends an email invitation. The site role to assign to the user. You can assign the following values for this attribute: SAML - The user signs in using the identity provider idP configured for the site.
ServerDefault - The user signs in using the default authentication method that's set for the server. For more information, see About multi-factor authentication and Tableau Online Link opens in a new window. Adds permissions to the specified view also known as a sheet for a Tableau Server user or group.
This method can only be called by server and site administrators, and user who have permission to set permissions on the workbook either explicitly or implicitly. To use this method, the parent workbook that contains the specified view must have its showTabs attribute set to Hide. You can configure this setting by using the Update Workbook method. This can apply to either an invalid capability name or an invalid capability value other than Allow or Deny.
Example of add-view-permissions. If the user already has the view listed as a favorite with the same label, the operation has no effect. Tableau Server users who are not server administrators or site administrators can call this method only if they have permission to add a view to a favorite list either explicitly or implicitly. The value of view-url-name is the name of the view in its URL.
Modifying the name display name of a view will not impact the view-url-name path element of the view's URL. Adds permissions to the specified workbook for a Tableau Server user or group. Tableau Server users who are not server administrators or site administrators can call this method only if the have permission to set permissions on the workbook either explicitly or implicitly.
If the user already has the workbook listed as a favorite with the same label, the operation has no effect. If the label is already in use for another workbook, an error is returned. Tableau Server users who are not administrators or site administrators can call this method only if they have permission to add a workbook to a favorites list.
A non-administrator user called this method but doesn't have permission to add a workbook to the specified user's favorites.
This will always be the case when the user references in the URI identifies a user other than the user who is calling the method. Adds a task to refresh or accelerate a workbook to an existing schedule. The task type must match the schedule type. For a list of schedule types, see Create a Schedule. Only Tableau Server users who are server administrators or site administrators can add a workbook to a data acceleration schedule.
Tableau Server users who are not server administrators or site administrators can only add a workbook to other types of schedules if they own the workbook, or are the project leader for the project that contains the workbook. Adds a dashboard extension to the safe list the site you are signed into.
Availability - Not available for Tableau Online. Uploads a block of data and appends it to the data that is already uploaded. This method is called after an upload has been initiated using Initiate File Upload.
You call Append to File Upload as many times as needed in order to upload the complete contents of a file. You get this value when you start an upload session using Initiate File Upload. The content of the file to be uploaded is included in a MIME multipart message.
For more information, see Publishing Resources. Tableau Server users who are not server administrators or site administrators can call this method only if they have publishing rights on the site. The maximum allowable size will be reported in the error response.
The type of data quality warning to apply to the content or asset. If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to batch add or update data quality warnings:.
If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to delete data quality warnings:.
If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to delete a data quality certification:. If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to delete data quality certifications:. If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to delete tags:.
Adds a dashboard extension to the block list of a server. Permissions - This method can only be called by server administrators. Cancels a job specified by job ID. To get a list of job IDs for jobs that are currently queued or in-progress, use the Query Jobs method. The job ID provided is for a job that has already succeeded or failed.
The event name must be one of the supported events listed in the Trigger Events table. The event and webhook-source use different name values for the same event.
Recommended: Use the event attribute of the webhook to specify the triggering API event for the webhook. The webhook-source element serves the same purpose but is being deprecated in future versions of Tableau webhooks.
If both events and webhook-source are specified, their events specified must match. If either are specified, with the other being NULL, then the specified event becomes the webhook trigger, whether the element containing the event name is event or webhook-source.
This method can only be called by server and site administrators. Create an extract for a data source in a site. Optionally, encrypt the extract if the site and workbooks using it are configured to allow it. If false , or no encrypt parameter is appended to the URI, then the extract won't be encrypted, unless encryption is enforced by site or workbook configuration. An error will be returned when encrypt equals true and encryption is disabled in the site or workbook.
Extracts for data sources can be created by Tableau server or site administrators, and by users who own the data source or are an owner or leader of the project where the data source resides. Create extracts for all embedded data sources of a workbook. Optionally, encrypt the extracts if the site and workbook using them are configured to allow it. When you create an extract for a data source in a workbook, the extract is available only to the workbook and may have configuration specific to the workbook, such as hiding of unused fields.
You can create workbook extracts for both embedded and published data sources used by the workbook. When you create a workbook data source for a published data source, then refreshing the workbook extract will retrieve any changes to data from the published datasource, or from the published data source's extract if it is using one. Note: This method will fail and result in an error if your Server Administrator has disabled the RunNow setting for the site.
For more information, see Tableau Server Settings Link opens in a new window. If true , then create extracts for all datasources embedded in a workbook. If false default , then a datasource must be specified in the request.
If true , then all data sources in the workbook will have an extract created for them. If false , then a data source must be supplied in the request. Extracts for data sources embedded in a workbook can be created by Tableau server or site administrators, and users who own the workbook, or are an owner or leader of the project where the workbook resides.
If Tableau Server or Tableau Online site is configured to use Active Directory for authentication, this method can create a group and then import users from an Active Directory group. To add users to a group, call Add User To Group. To make changes to an existing group, call Update Group. If you use the method to import users from an Active Directory, the import process can be performed immediately synchronously or as a background job asynchronously.
Note : If Active Directory contains a large number of users, you should import them asynchronously; otherwise, the process can time out. The Create Group response returns information in two ways: in the response header and in the response body. The ID of the new group is always returned as the value of the Location header. If you create a local group or import an Active Directory group immediately, the response body contains the name and ID of the new group.
You can use the job ID to check the status of the operation by calling Query Job. If you set this to false the default , the import process runs as a synchronous process. If the Active Directory group contains many users, the process might time out before it finishes.
If you set this to true , the process runs asynchronously. In that case, Tableau Server starts a job to perform the import and returns the job ID in the Location header. You can check the status of the import job by calling Query Job. Note : This parameter has no effect if the server is configured to use local authentication.
When the request is to create a local group and minimumSiteRole is specified, users are granted a license using the grant license on-login mode by default. When the request is to create a group with grantLicenseMode , a siteRole value should also be supplied.
Required if an import element or grantLicenseMode attribute are present in the request. The site role assigned to users who are imported from Active Directory or granted a license automatically using the grant license on-sync or on-login mode. If the requested user name matches an existing user in the group, the user either retains their existing role or are granted the one specified in the request, based on the role that enables the most capabilities. This is true whether the group the user belongs to is imported from Active Directory or local.
Site roles that can be assigned, listed from the one enabling the least capabilities to the most, are as follows. The mode for automatically applying licenses for group members. When the mode is onLogin , a license is granted for each group member when they log in to a site. For local groups, the mode can be either onLogin or unset.
If the attribute is omitted, the default mode is unset, which results in no licenses being granted automatically to group members.
For groups that import an Active Directory domain, the mode can be either onSync or onLogin. If the attribute is omitted, the default mode is onSync where licenses are granted for group members each time the domain is synced.
The minimum role granted to users through grantLicenseMode is specified in the siteRole attribute. If that role has less permissions than an existing role assigned to the user, then the user's permissions remain unchanged.
Creates a project on the specified site. You can also create project hierarchies by creating a project under the specified parent project on the site. To make changes to an existing project, call Update Project. When the publish-value is not specified in the request, or the publishSamples parameter is missing, no samples will be published.
To publish the sample workbooks, set publishSamples parameter to true. This option is equivalent to the tabcmd command-line utility option, publishsamples. For more information, see tabcmd Link opens in a new window. Use this option to create project hierarchies. For information about how permissions are evaluated in project hierarchies, see Project Permissions States and Defaults Windows Link opens in a new window Linux Link opens in a new window. However, if the project is nested within a project, it will inherit those permissions and these settings will have no effect.
The functional permissions of a project, including those it inherits, are available in value of contentPermission in the response body from a request to create, update, or query a project. The default is ManagedByOwner. For more information, see Lock Content Permissions Link opens in a new window. Schedules are not specific to sites. This name identifies the schedule in the server environment when users select a schedule and manage schedule information. Lower numbers have higher priority.
Jobs can be scheduled to at intervals specified in run one or more times per day at intervals specified in minutes or hours. The allowed intervals 15 and 30 minutes and 2, 4, 6, 8, and 12 hours. If the schedule frequency is Daily , no interval is specified.
Note: If you want to specify multiple days in the month, you can do this using the web interface. Content of create-schedule.
For a daily schedule, frequencyDetails is set to Daily. The start attribute is required. No intervals element is required. Daily schedules on any recurrence must have the same start and end minute. The hour can be different. However, if the daily schedule is set to only happen once a day, that it needs only a start time and not an end time.
For a weekly schedule, frequencyDetails is set to Weekly. A start attribute is required. The intervals element is required, and must include between 1 and 7 interval subelements that contain a weekDay attribute. For a monthly schedule, frequencyDetails is set to Monthly. The intervals element is required, and must include 1 interval subelement that contains a monthDay attribute. Valid values for the monthDay attribute are integers between 1 and 31 and the string LastDay. To make changes to an existing site, call Update Site.
This value can contain only characters that are valid in a URL. Specify ContentOnly to prevent site administrators from adding or removing users. Server administrators can always add or remove users. The default value is ContentAndUsers. Optional Specify true to prevent users from being able to subscribe to workbooks on the specified site.
The default is false. Optional Specify true to enable and false to disable editing flows for a site. The default is set to true which means editing flows is enabled by default. For more information, see Implication of disabling Tableau Prep Conductor. Optional Specify true to enable and false to disable scheduling flows for a site. The default is set to true which means scheduling flows is enabled by default.
The flowsEnabled attribute is deprecated as of API version 3. Optional If true , and subscription to attachments is enabled on the server, then users can create subscriptions that send an email with images of a workbook or view in a PDF attachment. The default value is true. If subscription to attachments is disabled in the server settings, then making this value true will have no effect.
Default is true. Optional Specify true to enable and false to disable the ability for guests, users without specific site access permission, to access the site. Default is false. Optional Set this value to true to enable cache warm up to improve workbook load time. Set the value to false to disable cache warmup. Optional Specify true to enable and false to disable the ability for user comments on views in the site.
Setting this value to -1 removes any value that was set previously, and effectively removes any limit to the number of revisions that are maintained. Optional Specify true to enable and false to disable the ability for view owners to subscribe other users to a view. Optional Specify enforced , enabled , or disabled. Default is disabled. For more information, see Extract and Encryption Methods. Optional Specify true to allow users to run flows, extract refreshes, and schedules manually.
Specify false if you do not want users to be able to run flows, extract refreshes, and subscriptions manually. The default is true. If this attribute is set to false , the following methods will fail and will return an error message. Run Flow Now. Run Flow Task Link opens in a new window.
Update Data Source Now Link opens in a new window. Run Extract Refresh Task Link opens in a new window. Licensing attributes For user-based license types, the maximum possible number of users is set by the licenses activated on that server. For core-based licensing, there is no limit to the number of users; if you specify a maximum value, only licensed users are counted, and server administrators are excluded.
The REST API enables administrators to set licensing limits below the purchased maximum with two types of license-related attributes: - User Quota - The total maximum number of licenses currently configured for a site. Online administrators can get these attributes. An on premise server administrator can both get and set them but if license maximums are set using one attribute kind then the value s of the other kind must be null.
Setting values for both kinds of attributes will result in an error. For more information, see Licensing Overview Link opens in a new window. Optional The maximum total number of users with Creator, Explorer, or Viewer licenses currently allowed on a site. On premise server administrators can set userQuota with the following rules: The number can't exceed the number of licenses activated for the site; and if tiered capacity attributes are set, then userQuota will equal the sum of the tiered capacity values, and attempting to set userQuota will cause an error.
An administrator can revert the license limit to number of activated licenses on the site, or shift control of license limits to tiered capacities values, by omitting userQuota from a Create Site or Update Site request, or making its value Optional The maximum number of licenses for users with the Creator, Explorer, or Viewer role, respectively, allowed on a site. On premise server administrators can set tiered capacity attributes with the following rules: the number can't exceed the number of licenses of a given type that are activated for the site; a value must be supplied for every tiered capacity license type every time any one or more of them is set.
A value of -1 removes the administrator applied limit for a license type, and reverts the limit to the number of activated licenses configured for the role. Setting the value of a tiered capacity to -1 will not automatically increase the limit if more licenses are purchased and activated for the role in the future. To use role-specific license limits, the userQuota must be set to null by omitting the attribute from Create Site or Update Site request, or setting its value to Attempting to set values for both tiered capacities and userQuota will result in an error.
Optional, boolean Set this attribute to false to disable Explain Data capabilities for a site. By default, this attribute is set to true. For more information about this site setting, see one of the following topics:. Optional, boolean Set this attribute to false to exclude data quality warnings DQWs from subscription emails. Note: An empty string or all whitespace is invalid. Creates a new, unsuspended subscription to a view or workbook for a specific user.
When a user is subscribed to the content, Tableau Server sends the content to the user in email on the schedule that's defined in Tableau Server and specified in this call. For more information, see Subscribe to Views Link opens in a new window in the Tableau Server documentation. This description is displayed when users list subscriptions for a site in the server environment.
A description is required. This is the default behavior if neither attachImage or attachPdf are specified. If subscriptions to attachments are disabled in Tableau server or site settings, then making a request that sets attachImage to false will cause an error.
Optional Setting this true will cause the subscriber to receive mail with a. If subscriptions to attachments are disabled in Tableau server or site settings, then making a request that sets attachPdf to true will cause an error. Note : The user must have an email address defined in Tableau Server. The following list summarizes the permissions required to subscribe a user to specific content:. The user does not have permission to create a subscription for the specified content. The user specified in the request body does not have Read view permissions for the specified content.
The user does not have an email address. Extract encryption at rest is a data security feature that allows you to encrypt. For more information, see Extract Encryption at Rest Link opens in a new window.
Note: Depending on the number and size of extracts, this operation may consume significant server resources. Consider running this command outside of normal business hours. Deletes a specific connection to an external service for analytics extensions on this site. To specify the type, use:. If Tableau Server or Tableau Online is licensed through the Data Management Add-on , the following users have permissions to delete the data quality warning:.
Optionally, you can also use RestTemplate. If the file size is large, then previous approach might cause OOM error and its better to use ResponseExtractor to stream the results from remote service without loading the file content into memory. RestTemplate provides the following two ways to download a file from a remote Http url:. Using byte array holding everything in memory Using ResponseExtractor stream the response instead of loading it to memory.
Option 1. Using byte array This is quite straight forward approach where we will use getForObject method to get a byte array from the remote service. Autowired; import org.
